| 802.1Q
802.1D |
802.1Q defines a layer 2 frame structure that supports VLAN identification and a QoS mechanism usually referred to as 802.1D. |
| 802.1X |
Authentication method for a protocol requiring a networking device to authenticate with a back end Authentication Server before gaining network access. Applicable 4600 Series IP telephones support IEEE 802.1X as a Supplicant with the EAP-MD5 authentication method. |
| ARP |
Address Resolution Protocol, used to verify that the IP Address provided by the DHCP server is not in use by another IP telephone. |
| CLAN |
Control LAN, type of TN799 circuit pack. |
| DHCP |
Dynamic Host Configuration Protocol, an IETF protocol used to automate IP Address allocation and management. |
| DiffServ |
Differentiated Services, an IP-based QoS mechanism. |
| IETF |
Internet Engineering Task Force, the organization that produces standards for communications on the internet. |
| LAN |
Local Area Network. |
| LLDP |
Link Layer Discovery Protocol. All IP Telephones with an Ethernet interface support the transmission and reception of LLDP frames on the Ethernet line interface in accordance with IEEE standard 802.1AB. |
| MAC |
Media Access Control, ID of an endpoint |
| PAE |
Port Access Entity. The protocol entity associated with a port. The PAE supports the protocol functionality associated with the authenticator, supplicant, or both. |
| QoS |
Quality of Service, used to refer to several mechanisms intended to improve audio quality over packet-based networks. |
| RRQ |
Read Request packet. A message sent from the 4600 Series IP Telephone to the TFTP server, requesting to download the upgrade script and the application file. |
| SES |
SIP Enablement Services. Supports the deployment of duplicated servers with synchronized databases. |
| SIP |
Session Initiation Protocol. An IETF standard protocol for IP communication. SIP enables IP telephony gateways, client endpoints, PBXs, and other communication systems or devices to communicate with each other. SIP mainly addresses the call setup and tear down mechanisms of sessions and is independent of the transmission of media streams between caller and callee. SIP is an alternative to H.323 for VoIP signaling. |
| Supplicant |
An entity at one end of a point-to-point LAN segment that is being authenticated by an authenticator at the other end of that link. |
| TCP/IP |
Transmission Control Protocol/Internet Protocol, a network-layer protocol used on LANs and internets. |
| TFTP |
Trivial File Transfer Protocol, used to provide downloading of upgrade scripts and application files to the IP telephones. |
| UDP |
User Datagram Protocol, a connectionless transport-layer protocol. |
| Unnamed Registration |
Registration with Avaya Communication Manager by an IP telephone with no extension. Unnamed registration is typically used to limit outgoing calling. |
| VLAN |
Virtual LAN. |
